管道独立改革有效性的博弈分析

Is Pipeline Splitting an Exhaustive Approach to Solve the Problem of Pipeline Repeated Construction

通过建立双寡头油气企业管输量的Hotelling模型分析管道独立改革在促进油气价格市场化和解决管道重复建设问题中的作用,得出四点结论:油气企业总是存在自建管道的动机;油气企业对独立管道公司的依赖程度越高,油气企业的利润越低;高成本油气企业可以通过管输量优势降低甚至扭转其在市场竞争中的劣势;独立管道公司有过度提高单位油气运输价格的动机。并提出四点政策建议:为保证改革的有效性,政府需要禁止油气企业自建管道;协调独立管道公司和油气企业之间管输利润的分配关系;采取措施防止出现竞争失衡状况,始终使油气市场保持充分的竞争性;对管道公司管输定价进行监管,防止其利用市场势力损害消费者利益。

Through establishing Hotelling model about the throughput of pipeline of duopoly oil and gas companies to analyze the influence of pipeline splitting reform on oil and gas market-oriented price reform and pipeline repeated construction,this paper draws four conclusions that oil and gas companies are always motivated to build pipeline by themselves;the higher degree of dependence upon pipeline company, the lower profits they will earn;high-cost company can reduce or even reverse its disadvantage in market competition by gaining the advantage of throughput of pipeline; and pipeline companies have an incentive to enhance the transport price for unit oil and gas. And putting forward four policy suggestions that government needs to forbid oil and gas companies building pipeline by themselves;to coordinate profit distribution between pipeline companies and oil and gas companies; to take measures to prevent the competitive imbalances fully keeping oil and gas markets competitive;and to execute price regulation on pipeline companies to prevent them from using market power to harm the interests of consumers.
